迟后-超前对数频率解析法校正

Design Lag-lead Compensation Devices of Analytic Method of Logarithmic Frequency Character

为了提高控制系统迟后超前校正装置的设计精度和速度 ,采用对数频率特性的解析法代替对数频率特性的作图法 。

For raisimg design accuracy and speed of laglead compensation devices,applying an analytic method of logarithmic frequency character replaces method of Bode diagram design.This method can avoid the difficulties ties of trial parameter and drawing phase curve.
